So my truck has a commodore engine, commodore rad hoses, and steel heater pipes up to the firewall.
The radiator is probably from another mitsubishi, or a modified original, and I have the standard 1st gen heater core.
The radiator cap that was on the truck when I got it was a 13psi cap. The commodore would have had a 20psi cap.
I don't lose fluid, but the overflow tank does gain some when it heats up. Engine doesn't seem to over heat (gauges are not reliable, nor is the Internet for where they should sit)
I think I will swap out the cap for the 20psi one, as that's what the engine was designed for. But my concern is that the heater core or radiator may not agree with the higher pressure
Has anyone ran a high pressure cap on their truck and had problems with the radiator or heater? Obviously I'm not too worried if something fails because it's old and corroded, more if a good condition system just isn't up to it
-gauge seems to sit at half cruising on the highway, gets up to 3/4 with city driving, but never higher even on the hottest day in the worst city traffic. Internet says it shouldn't even get past 1/4 for the vp engine. VR engine should sit around where mine does
